Description

Powersoft Amplifiers Duecanali 804

Overview

The ability to implement any configuration with ease makes the Duecanali series extremely flexible. Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum.

The Duecanali 804 is designed to work with Lo-Z (from 2 Ω ) and with 70V/100V distributed lines: any mixed impedance output loads can be realized.

Features

Power supply

  • Powersoft legendary universal switch-mode power supply up to 400VAC tolerant with Power Factor Correction
  • Patented output filter with ripple cancellation network
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
  • Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for the USA) socket

Protections

Fully protected circuit design with:

  • Ac protection: shut down the power supply when AC mains voltage is outside the operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against non-audible, strong, non-musical high-frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long-term limiter: protects the loudspeaker against steady long-term RMS (non-audio) signals, by reducing the maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature-controlled continuous variable speed fan, front-to-back airflow
  • Temperature forecast with LCD traced historical behavior.

General

  • Fixed frequency switch-mode output stage for high-grade sound accuracy
  • Compact size – all models only 1 RU for reduced rack cost and space
  • Lightweight – for easier racking and shipping: 7 kg (15.4 lbs)
  • Standard Phoenix connectors: analog audio outputs, aux supply, alarms and GPIO
  • Remotely switchable double input (main and aux) per channel

Loudspeaker system configuration

  • Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
  • Switchable 35Hz / 70Hz high pass filter per channel
  • Mixed configuration with Lo-Z/Hi-Z systems possible
  • Bridged mode low impedance per channel pair

Alarms and GPI/O

  • NC/NO contacts per channel for alarm notifications
  • Remote ON/OFF switch
  • Remote VCA control per channel

Remote Control & Monitoring

Via Software:

  • Attenuation (from 0 dB to 26 dB)
  • Max output voltage
  • Output and gain reduction metering
  • Diagnostics (temperature, fans, …)

Via Hardware:

  • Attenuation (from 0 dB to 26 dB)
  • High Pass Filter (35 Hz, 70 Hz)
  • LoZ/HiZ/70V/100V output selection
  • Gain (from 26 dB to 35 dB)
